EULAR points to consider for the diagnosis and management of rheumatic immune-related<br \/>\nadverse events due to cancer immunotherapy with checkpoint inhibitors. Ann Rheum Dis 2021;80:36\u201348.<br \/>\ndoi:10.1136\/annrheumdis-2020-217139<\/p>\n<p><strong>Introduction<\/strong><br \/>\nEULAR recommendations give advice to doctors, nurses and patients about the best way to treat and<br \/>\nmanage diseases. EULAR has written new \u2018points to consider\u2019 on how to diagnose and manage rheumatic<br \/>\nimmune-related side effects in people taking a type of cancer drug called a checkpoint inhibitor.<br \/>\nDoctors, nurses, other health professionals and patients worked together to develop this advice. The patients<br \/>\nin the team ensured that the patient point of view was included.<\/p>\n<p><strong>What do we already know?<\/strong><br \/>\nCheckpoint inhibitors act on the immune system to treat several types of cancer. This group of drugs<br \/>\nincludes ipilimumab, nivolumab, pembrolizumab, cemiplimab, atezolizumab, avelumab and durvalumab.<br \/>\nAbout 10% of people who take a checkpoint inhibitor drug to treat a cancer develop musculoskeletal side<br \/>\neffects called immune-related adverse events (shorted to irAEs).<br \/>\nEULAR has written a set of \u2018points to consider\u2019 on how rheumatic irAEs should be diagnosed and managed.<br \/>\nThese aim to help oncologists and rheumatologists work together to treat people who develop these side<br \/>\neffects. At the moment there is a very low level of evidence on this subject, so it is not possible to develop full<br \/>\nrecommendations.<\/p>\n<p><strong>What do the points say?<\/strong><br \/>\nIn total, there are 4 overarching principles and 10 points to consider. The principles highlight that these<br \/>\nrheumatic and musculoskeletal irAEs are common in people taking checkpoint inhibitors, and should be<br \/>\nmanaged on a shared-decision basis between patients, their treating oncologist, and the rheumatology team.<br \/>\nRheumatologists should work to assist the oncologist in differential diagnosis, and help to relieve symptoms<br \/>\nto enable patients to maintain their cancer immunotherapy.<br \/>\nEach point is based on the best current knowledge and studies of scientific evidence or expert opinion. The<br \/>\nmore stars a point has the stronger the evidence is. However, even recommendations with limited scientific<br \/>\nevidence may be important, because the experts may still have a strong opinion and the evidence may be<br \/>\nlagging behind.<br \/>\nOne star (*) means it is a recommendation with limited scientific evidence.<br \/>\nTwo stars (**) means it is a recommendation with some scientific evidence.<br \/>\nThree stars (***) means it is a recommendation with quite a lot of scientific evidence.<br \/>\nFour stars (****) means it is a recommendation supported with a lot of scientific evidence.<\/p>\n<p><strong>\u2022 Rheumatologists should be aware of the wide spectrum of rheumatic immune-related adverse<\/strong><br \/>\n<strong>events that often do not fulfil traditional criteria of rheumatic diseases.*<\/strong><br \/>\nThere is a lot of variation in the types of irAEs that people get from checkpoint inhibitors. These can<br \/>\ninclude arthritis and joint pain, myositis, dry mouth, skin thickening, fever, fatigue, etc. Rheumatologists<br \/>\nshould be aware of the possible symptoms that can mimic rheumatic diseases.<\/p>\n<p><strong>\u2022 Oncologists should consult rheumatologists quickly when rheumatic symptoms are suspected<\/strong><br \/>\n<strong>due to immunotherapy, and rheumatologists should provide access for these patients.*<\/strong><br \/>\nIf people taking checkpoint inhibitors develop rheumatic irAEs, their treating oncologist should quickly<br \/>\nrefer them to a rheumatologist, ideally before trying any steroid treatment. Rheumatologists should see<br \/>\nthese patients quickly as they are best-placed to try low-dose or steroid-sparing treatments.<\/p>\n<p><strong>\u2022 Some side effects of the cancer itself or unrelated rheumatic diseases might look like immune-<\/strong><br \/>\n<strong>related events. Clinical evidence, laboratory tests, imaging and biopsies should be collected to<\/strong><br \/>\n<strong>search for inflammation and exclude other diseases.*<\/strong><br \/>\nCheckpoint inhibitors are often used in people with advanced cancer, and so new rheumatic or<br \/>\nmusculoskeletal symptoms may not always be irAEs. The oncology team should collect clinical evidence<br \/>\nto rule out cancer progression. It is important that this is done quickly to ensure the correct treatment can<br \/>\nbe given. Then, the rheumatologist should collect evidence of inflammation (on joints, on muscles, on<br \/>\nvessels, etc&#8230;) either by clinical evidence, or blood tests and imaging, and if required with biospies.<\/p>\n<p><strong>\u2022 If other treatments do not work, steroids can be considered for symptoms that look like immune-<\/strong><br \/>\n<strong>related rheumatic or connective tissue diseases.*<\/strong><br \/>\nIf treatment with painkillers or non-steroidal anti-inflammatory drugs does not work to control your<br \/>\nsymptoms, you may be offered glucocorticoids (steroids). This will depend on your particular set of<br \/>\nsymptoms, but steroids injections or tablets can be useful for arthritis or joint pain. Once your irAE<br \/>\nsymptoms have improved, the steroid should be reduced to the lowest dose needed to maintain control.<br \/>\nThis is because steroids used for a long time or at a high dose can cause side effects or may alter how<br \/>\nyour tumour responds to treatment.<\/p>\n<p><strong>\u2022 csDMARD should be considered in people with insufficient response to glucocorticoids or those<\/strong><br \/>\n<strong>requiring glucocorticoid-sparing.*<\/strong><br \/>\nIf steroids do not work to control your symptoms \u2013 or if they only work for you at a high dose (more than<br \/>\n10 mg per day) \u2013 then you may be offered a conventional synthetic disease-modifying antirheumatic<br \/>\ndrug instead (often shortened to csDMARD). These types of drugs include methotrexate,<br \/>\nhydroxychloroquine or sulfasalazine.<\/p>\n<p><strong>\u2022 bDMARDs can be considered for people with severe rheumatic and connective tissue disease-<\/strong><br \/>\n<strong>like immune-related adverse events or those with insufficient response to csDMARDs.*<\/strong><br \/>\nPeople experiencing severe rheumatic and systemic irAEs, or those with an insufficient response to<br \/>\ncsDMARDs can try a biologic (also called a bDMARD). For people with symptoms of inflammatory<br \/>\narthritis, the preferred options are TNF or IL-6 inhibitors.<\/p>\n<p><strong>\u2022 The decision to stop or to continue cancer immunotherapy should be made with the patient,<\/strong><br \/>\n<strong>based on side effect severity, the tumour response and duration, and the treatment plan.*<\/strong><br \/>\nAt the moment there is no agreement about whether people with irAEs should stay on the checkpoint<br \/>\ninhibitor. This might vary depending on your country or treating team, but you should be involved in the<br \/>\ndiscussions and decision-making.<\/p>\n<p><strong>\u2022 Myositis may be a severe condition, and stopping cancer immunotherapy needs to be discussed.<\/strong><br \/>\n<strong>If there are life-threatening symptoms, other treatment options can be used instead.*<\/strong><br \/>\nMyositis is inflammation in a person\u2019s muscles, causing weakness and pain. Myositis can also affect the<br \/>\nmuscles of the heart, which can potentially be fatal. If myositis is suspected, it may be necessary to stop<br \/>\nthe checkpoint inhibitor. People who have life-threatening symptoms such as dysphagia, dysarthria,<br \/>\ndysphonia, dyspnoea or myocarditis can be treated with high-dose glucocorticoids, intravenous<br \/>\nimmunoglobulin (IVIg) and\/or plasma exchange.<\/p>\n<p><strong>\u2022 Cancer immunotherapy can be used in people who have a pre-existing autoimmune rheumatic<\/strong><br \/>\n<strong>disease, while keeping their immunosuppressive treatment for the rheumatic disease at the<\/strong><br \/>\n<strong>lowest dose possible.*<\/strong><br \/>\nPeople with pre-existing inflammatory or autoimmune diseases can take checkpoint inhibitors for cancer,<br \/>\nbut they and their treating team should be aware that they may experience disease flares. In most cases,<br \/>\nthese flares can be managed with steroids.<\/p>\n<p><strong>\u2022 There is no need to test for autoantibodies before starting cancer immunotherapy, but these<\/strong><br \/>\n<strong>should be checked if there are rheumatic, musculoskeletal or systemic symptoms.*<\/strong><br \/>\nAutoantibodies are not always present in people with irAEs, so there is no need to test everyone before<br \/>\nthey start treatment with a checkpoint inhibitor. However, it can be useful as part of a complete<br \/>\nrheumatology assessment if you have unexplained rheumatic, musculoskeletal or systemic symptoms.<\/p>\n<p><strong>Summary<\/strong><br \/>\nOverall, these points to consider provide the basis of a EULAR consensus in a new and rapidly expanding<br \/>\nfield. Early consultation and strong collaboration between the referring oncologist, the treating<br \/>\nrheumatologist, other organ specialists and the patient are all required for optimal management.<br \/>\nRecommendations with just one or two stars are based mainly on expert opinion and may not be backed up<br \/>\nsufficiently yet by studies. These may be as important as those with three or four stars.<br \/>\nIf you have any questions or concerns about your disease or your medication, you should speak to a health professional involved in your care.<\/p>\n<p><strong>Disclaimer<\/strong>\u00a0: This is a summary of a scientific article written by a medical professional (\u201cthe Original Article\u201d).
